The Murder of Kathleen Flynn (Connecticut)

For nearly 40 years, Kathleen Flynn’s murder has haunted Norwalk, Connecticut. She was 11 years old, newly in middle school, walking home on a familiar path when she was attacked and killed. Her case became one of the state’s most well-known cold cases, the kind people never stopped talking about, and the kind investigators kept returning to as forensic science moved forward. 

In 2019, after decades of waiting, police finally made an arrest. And in 2026, it looked like Kathy’s family might finally see the case reach a verdict. But then, just days into trial, a single email threatened to undo that long-awaited progress. Now, the question is no longer just what happened to Kathy, but what happens next.

Kathleen Flynn’s case is still open. Anyone with information should contact Lieutenant Art Weisgerber at the Norwalk Police Department. You can call him directly at 203-854-3028 or email aweisgerber@norwalkct.org.

September 23, 1986

On Tuesday, September 23rd, 1986, the school day at Ponus Ridge Middle School in Norwalk, Connecticut ended the same way it always did, with the 2:40 bell.

Students spilled out into the hallways. Some headed for buses. Some went to after-school activities. Outside, the soccer and field hockey teams were practicing on the fields. And 11-year-old Kathleen Marie Flynn, who usually went by Kathy, went to her locker and organized some papers inside before she packed up her white duffle bag and left school for the day.

Kathy was only a few weeks into her middle school career and she’d started walking home from school that fall; it was short, only about a half-mile from Ponus Ridge Middle School to her house on Kendall Court. And like a lot of kids in the neighborhood, she took the shortcut through the wooded area behind the school, a paved footpath that cut from campus to Hunters Lane.

Most days, Kathy walked that path with a few friends. But that afternoon, she was alone. According to reporting by Marissa Alter for News12, one friend had gotten a ride home, and another was home sick from school.

Kathy was supposed to meet her mother, Esther Flynn, at a nearby intersection by 3:30 that day. They had plans that afternoon to go shopping for a new purse for Kathy. Esther was running a little late, but not by much.

When she got to the meeting spot, Kathy wasn’t there. At first, there were still normal explanations. Maybe Kathy had walked home. Maybe she had stopped somewhere. Maybe she had followed through on something she’d mentioned earlier, that she wanted to visit her fifth-grade teacher at her old elementary school.

When Esther got home, Kathy wasn’t there either. She went to the elementary school, but no Kathy. A check of Kathy’s locker at the middle school showed that her bag and other belongings were gone. By a little after 5 p.m., she was still missing.

At 5:12 p.m., Esther Flynn filed a missing persons report with the Norwalk Police Department. Esther gave a description of Kathy’s outfit that day: a whale watcher T-shirt, paisley jeans, and pink sneakers.

Officers collected a pillowcase and T-shirt from Kathy’s home so search dogs could use her scent  and then Kathy’s older brother went with them to point out the path Kathy usually took home from school.

Norwalk Police searched the wooded area with the fire department. It was not easy terrain to search, especially in late September. The area was heavily wooded, with thick brush and fallen leaves covering the ground.

As the night stretched into the early morning hours of September 24th, the searchers began finding pieces of Kathy’s afternoon. At about 2 a.m., officers found a white canvas duffle bag stuffed under two branches. It matched the description of Kathy’s school bag, and inside was a book with her name in it.

About 20 feet away, a tracking dog found Kathy’s pink Reebok sneakers with the laces untied.

The dog kept searching and circled an area of heavy brush and branches, but then moved on. Human searchers continued through the area and found two pink socks, one on the ground and another caught on a branch.

Then, around 3:30 that morning, an officer noticed a pile of brush that didn’t look right. He moved a log from the pile and found Kathy’s body underneath. She was just under 160 feet from the footpath. A large rock had been placed on her chest. She was lying face up and wearing only a black T-shirt.

Even before a complete post-mortem examination was performed, investigators at the scene could see a clear ligature mark around Kathy’s neck. There was also evidence that her wrists had been bound with three or four rows of ligatures, though the bindings themselves had been removed.

The autopsy would later confirm the violence. The medical examiner documented tiny hemorrhages in Kathy’s eyelids and on her face, along with dried ligature furrows on her neck. The autopsy also documented injuries consistent with sexual assault, though swabs did not detect the presence of spermatozoa.

Evidence was collected from Kathy’s body, including hair, fingernail scrapings, blood, one earring, a chain, and a T-shirt. Among the hair evidence were hairs found in Kathy’s pubic area and in her right hand.

Kathy’s cause of death was listed as asphyxia due to ligature strangulation. Her manner of death was homicide.

Only hours earlier, Kathy had been at school, organizing papers in her locker and walking out with her bag to meet the safe arms of her mother. And in the days and weeks that followed, that was the part of the story people in Norwalk could not get away from: Kathy had been a child doing something ordinary, in a place that was supposed to be safe.

About Kathy Flynn

Kathy’s birthday was on September 4th, only 19 days before she was killed. She got a new bike. It was lavender.

By all accounts, she was the kind of sixth grade student teachers love to have in class. She loved learning, and she wasn’t afraid to ask questions when she wanted to understand something better.

At home, Kathy was starting to take on more responsibility. She wanted to grow up. She wanted to be helpful and capable and independent, the way kids do when they’re right on the edge of feeling bigger than they are. But she was also still very much 11 years old. Mark Pazniokas reports for the Hartford Courant that Kathy collected Strawberry Shortcake dolls. She had a dog named Lady, who waited for her to come home from school everyday.

Joseph Queen reports for the Stamford Advocate that Kathy’s father ran a seafood and hamburger restaurant on the water in a nearby town, and her mother was a school teacher. Kathy sometimes helped her father at the restaurant, which is how she earned the money to buy those pink sneakers she was wearing to school that day. Kathy was proud of those sneakers.

Kathy’s murder shook Norwalk to its core. Kathy did not vanish from somewhere remote or unknown. She disappeared during the narrow window between the school bell and the moment she was supposed to meet her mother. With that, people in Norwalk started replaying what they had seen near the school that day. Every car. Every stranger. Every detail that might not have seemed important until suddenly it was.

Early Investigation

Norwalk police were flooded with calls. Detectives were also actively talking to students, and some of them described people or vehicles that seemed out of place near the footpath on Hunters Lane around dismissal time.

One tip involved an incident from earlier that month, on September 2nd. According to reporting, a man in either a red Porsche or a Mazda RX-7 had allegedly tried to lure a 9-year-old girl into his car in the New Canaan Avenue area, about a mile from where Kathy’s body was found. The man was described as white, between 25 and 35 years old, with a gruff voice.

Another early lead came from a student who claimed he had seen Kathy get abducted by three men. That tip seemed to line up, at least at first, with another report involving a suspicious green car seen near the school.

A witness named Fran said that at around 3:50 p.m. on September 23rd, she saw a car come speeding out of the middle school footpath area onto Ponus Avenue, nearly hitting her car. She was able to see in her rearview mirror that the car had New York plates and described it as older but in fair condition, possibly a 1969 Chevrolet, though she was not certain.

She said there were three white male teenagers inside. The driver had dirty blond hair and was wearing a white T-shirt, and the rear passenger had a darker complexion.

Police released composite sketches of two people believed to have been seen in the car, and all three men were described as suspects in the Connecticut Post and other reporting.

Fran was not the only person talking about three men near the school. According to reporting, six witnesses total said they had seen three men near the area of Kathy’s murder around the time of the crime. Some witnesses said the men were near the woodsline as classes let out at 2:40 p.m., and investigators believed they may have been the same men seen speeding away in the green car around 3:45 p.m.

At the same time, detectives were still processing the physical scene. Between September 24th and September 26th, police searched the area and recovered additional clothing but they did not find Kathy’s underwear, jeans, bra, the other gold heart earring missing from her right ear, or any of the ligatures that may have been used by the person who killed her.

Then, on October 8th, officers went back for a secondary search of the area around the crime scene. They used rakes to clear through debris, and during that search, an officer noticed a pile of rocks that looked out of place. When he moved one of the rocks, he found a light blue and white paisley-print garment underneath.

The garment matched the description of Kathy’s missing pants. Detectives were called, the pants were photographed where they were found, and Kathy’s mother later positively identified them as the pants Kathy had worn to school the day she disappeared.

At the same time police were chasing the green car lead, interviewing students, and trying to figure out whether the report of three men near the school was real, another suspect entered the investigation for a different reason. Not because of forensic evidence, at least not yet. Not because a witness had identified him on the path either. But because of another case from earlier that same year; a sexual assault case with details that sounded uncomfortably familiar. The suspect was Marc J. Karun.
